Shallow sea raft culture method suitable for healthy and efficient growth of shellfish

Abstract

The invention provides a shallow sea raft culture method suitable for healthy and efficient growth of shellfish. The technical scheme is described as follows: the method comprises iron anchor fixing rings (1), floaters (2), lifting ropes (3), clamping lugs (4), cross rods (5), floater fixing rings (6), vertical rods (7), mooring ropes (8), iron anchors (9), culture cages (10), rope slings (11), valve rods (12), lower-layer valve rods (13) and upright rods (14). According to the method, raft culture is carried out from a near shore to a far shore and then at different sea areas of the near shore at different time periods, so that the cultured shellfish can be enabled to grow in an appropriate water environment all the time; by drawing up distribution points of a culture sea area, the water environment is monitored regularly, so that the quality and the yield of the shellfish can be ensured.

Description

technical field [0001] The invention relates to the technical field of shallow sea culture, in particular to a shallow sea raft culture method suitable for the healthy and efficient growth of shellfish. Background technique [0002] In shallow sea raft farming of shellfish, with the continuous expansion of the scale of farming, the safety problems of shellfish farming are becoming more and more prominent. The deterioration of the farming environment, the decline of the quality of the cultured shellfish, and the outbreak of diseases have seriously hindered the shellfish farming. healthy and sustainable development of the industry. Shellfish breeding areas are mostly located in bays near the shore, where the wind and waves are small, the seawater exchange capacity is poor, and they are greatly affected by the discharge of land-based sewage. In addition, shellfish farming raft-type pile foundations are fixed, and shellfish farming cages are tied to piles. On the cable, when th...

[0002] In shallow sea raft farming of shellfish, with the continuous expansion of the scale of farming, the safety problems of shellfish farming are becoming more and more prominent. The deterioration of the farming environment, the decline of the quality of the cultured shellfish, and the outbreak of diseases have seriously hindered the shellfish farming. healthy and sustainable development

Shellfish breeding areas are mostly located in bays near the coast, where the wind and waves are small, the seawater exchange capacity is poor, and they are greatly affected by the discharge of land-based sewage. In addition, the pile foundations for shellfish farming are fixed, and the shellfish farming cages are tied to the piles. On the cable, when the breeding environment changes or is polluted, the cultured shellfish cannot avoid it. Severe pollution often leads to the occurrence of diseases, reduces the quality and output of the cultured shellfish, and causes serious economic losses to the farmers.
